All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The refrigerator that this application embodiment provided can be two refrigerator door, and of course, the refrigerator also can be single refrigerator door or three refrigerator doors. Referring to fig. 1 to 4, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present disclosure, fig. 2 is a schematic flow direction diagram of air in a first compartment cooling state of the refrigerator shown in fig. 1, fig. 3 is a schematic flow direction diagram of air in a second compartment cooling state of the refrigerator shown in fig. 1, and fig. 4 is a schematic flow direction diagram of air in the first compartment and the second compartment cooling state of the refrigerator shown in fig. 1. The refrigerator may include a cabinet 10, a door 20, a circulation fan, and an evaporator 30. The box body 10 has a storage compartment 40 therein, and one side of the storage compartment 40 is opened for a user to put in and store products such as food. The door 20 is movably installed on the body 10, and thus can open or close the storage compartment 40. An evaporator 30 is provided in the cabinet 10 as a heat exchanger to convert hot air into cold air. The circulating fan is also arranged in the box body 10 to blow cold air generated by the evaporator 30 into the storage compartment 40, so as to refrigerate the storage compartment 40 and finally refrigerate products such as food.

Due to different storage temperatures required for different products, a plurality of compartments are often disposed inside the box body 10 as the storage compartment 40, for example, the storage compartment 40 includes a first compartment 410 and a second compartment 420. The first compartment 410 may be provided with a freezing compartment or a refrigerating compartment as required. The second compartment 420 may be provided with a freezing compartment or a refrigerating compartment as required. In the related art: the first compartment 410 and the second compartment 420 are communicated, and the evaporator 30 and the circulation fan are disposed in the first compartment 410. Therefore, the cool air generated from the evaporator 30 can cool the first compartment 410 and the second compartment 420 simultaneously by the circulation fan. Therefore, the refrigerator in the related art cannot realize independent refrigeration of one compartment.

As shown in fig. 1, in the embodiment of the present application, the refrigerator includes a cabinet 10. The cabinet 10 has therein a first compartment 410, a second compartment 420, and an evaporator chamber 50. Evaporator chamber 50 is in communication with first compartment 410 and evaporator chamber 50 is in selective communication with second compartment 420. Meanwhile, the evaporator 30 is provided in the evaporator chamber 50 to produce cool air, and a first blower 60a is further provided in the evaporator chamber 50, and the first blower 60a can blow the cool air in the evaporator chamber 50 into the first compartment 410 and the second compartment 420. At this time, as shown in fig. 4, if the evaporator chamber 50 communicates with the second compartment 420 and the evaporator 30 and the first blower 60a are simultaneously operated, the cool air generated from the evaporator 30 can be simultaneously blown into the first compartment 410 and the second compartment 420 by the first blower 60a, thereby achieving simultaneous cooling of the first compartment 410 and the second compartment 420. If the evaporator cavity 50 and the second compartment 420 are not communicated, when the evaporator 30 and the first fan 60a are simultaneously operated, as shown in fig. 2, the cold air generated from the evaporator 30 may be blown into the first compartment 410, thereby achieving the independent refrigeration of the first compartment 410. To achieve the individual cooling of the second compartment 420, a second blower 60b is provided at a sidewall forming the second compartment 420, and the second blower 60b may draw the cool air in the evaporator chamber 50 into the second compartment 420. Therefore, when the second compartment 420 is communicated with the evaporator chamber 50, if the first fan 60a is not operated, the second fan 60b and the evaporator 30 are operated at the same time, as shown in fig. 3, the cold air generated from the evaporator 30 can be drawn into the second compartment 420 by the second fan 60b, thereby achieving independent cooling of the second compartment 420.

As shown in fig. 1, the evaporator chamber 50 can have a first section 510, a second section 520, and a third section 530. Wherein the first segment 510 is obliquely arranged, an upper portion of the first segment 510 is disposed in a sidewall forming the second compartment 420 and selectively communicates with the second compartment 420, and a lower portion of the first segment 510 is disposed in a sidewall forming the first compartment 410. Wherein the second section 520 is vertically arranged and disposed in the sidewall forming the first compartment 410. The upper end of the second section 520 communicates with the lower end of the first section 510. The sidewall forming the first compartment 410 is further provided with a second vent hole 411, and the second vent hole 411 communicates the first compartment 410 and the second section 520. Wherein the third segment 530 has a third end 531 and a fourth end 532 disposed opposite to each other. The evaporator 30 is mounted on the side wall forming the third section 530, and the fourth end 532 communicates with the upper end of the second section 520. A first fan 60a is mounted on a side wall forming the fourth end 532.

Therefore, when the evaporator 30 and the first fan 60a operate simultaneously, as shown in fig. 4, after the cold air generated by the evaporator 30 is blown into the second section 520 by the first fan 60a, one path of the cold air is blown into the second compartment 420 through the first section 510, and the other path of the cold air is blown into the first compartment 410 through the second vent 411, so that one evaporator 30 can simultaneously refrigerate two compartments in cooperation with the first fan 60 a.

Wherein the third segment 530 may be laterally disposed, i.e., the third end 531 and the fourth end 532 are flush. It will be appreciated that the transverse disposition of the third section 530 results in an increased thickness of the side wall forming the evaporator chamber 50, and ultimately increases the footprint of the refrigerator. To this end, as shown in fig. 1, in the present embodiment, the third segment 530 is vertically disposed and juxtaposed with the second segment 520.

The first fan 60a may be an axial flow fan, a mixed flow fan, a cross flow fan, or the like.

As shown in fig. 1, there may be a plurality of second ventilation holes 411, and a plurality of second ventilation holes 411 are arranged in an array on a sidewall that partitions the second section 520 and the first compartment 410. Through the arrangement of the second ventilation holes 411, the cold air can be blown into the first compartment 410 more uniformly, so that the temperature difference in the first compartment 410 is smaller.

As shown in fig. 1, in the embodiment of the present application, a damper 70 may be provided on a sidewall forming the first section 510 to enable selective communication between the evaporator chamber 50 and the second compartment 420, the damper 70 being located at an upper portion of the first section 510. Specifically, the damper 70 may be an electrically operated damper that includes a power source and a partition. The power source may be an electric push rod, a servo motor, etc., and the power source may drive the partition plate to rotate and then partition the second section 520 and the second compartment 420, or the power source may drive the partition plate to horizontally move and then partition the second section 520 and the second compartment 420, thereby achieving communication between the evaporator cavity 50 and the second compartment 420. It will be appreciated that the amount of cold air blown into the second compartment 420 by the first fan 60a can be controlled, and thus the temperature of the second compartment 420 can be adjusted, depending on the degree of blocking of the communication between the evaporator chamber 50 and the second compartment 420 by the partition.

The first compartment 410 is configured such that the internal temperature can be adjusted between-18 c and 5 c, and thus the first compartment 410 can be adjusted into a wide temperature-variable compartment or a freezing compartment according to the use requirement. The inner surface of the first compartment 410 is provided with a first foamed layer. Since the first foaming layer has a good heat insulation effect, heat exchange between the first compartment 410 and the outside can be reduced.

As shown in fig. 1, a first air return hole 412 is further formed on a side wall forming the first chamber 410, and the first air return hole 412 is located at a bottom of the first chamber 410 and communicates the first chamber 410 and the fourth end 532. Therefore, the cool air blown into the first compartment 410 from the second ventilation hole 411 can flow into the fourth end 532 through the first return hole 412, and the third section 530, the second section 520 and the first compartment 410 of the evaporator chamber 50 form an air circulation path inside the cabinet 10. In order to prevent the first air return hole 412 from being blocked, a baffle 413 located in the first compartment 410 is disposed on a side wall forming the first air return hole 412. The free end of the baffle 413 is bent downward.

The second compartment 420 is configured to be temperature-regulated between 2 c and 8 c, and further, may be regulated as a freezing compartment or a refrigerating compartment. The inner surface of the second compartment 420 is provided with a second foaming layer, and the second foaming layer has a good heat preservation effect and can reduce heat exchange between the second compartment 420 and the outside. The box 10 forms a second compartment 420 and a second opening 421 is formed on a side wall facing a user for the user to access a product in the second compartment 420. Accordingly, as shown in fig. 2, the door 20 includes a second door 220, and the second door 220 is disposed on a sidewall forming a second compartment 420 so that a user can open or close the second compartment 420.

In the embodiment of the present application, as shown in fig. 1, the side wall forming the second compartment 420 is further provided with a vertically arranged wind chamber 80, and the second compartment 420 is indirectly communicated with the evaporator chamber 50 through the wind chamber 80. Specifically, the air chamber 80 is located above the evaporator chamber 50 and communicates with the evaporator chamber 50. In other embodiments, the bottom wall forming the air chamber 80 includes a bottom wall adjacent to the evaporator chamber 50, and the bottom wall is provided with a damper 70, wherein the damper 70 can isolate the air chamber 80 from the evaporator chamber 50 to realize the selective communication between the second compartment 420 and the evaporator chamber 50. The damper 70 is located below the second fan 60 b. In the embodiment of the present application, a first vent 810 is further disposed on a side wall forming the wind chamber 80, and the first vent 810 communicates the wind chamber 80 and the second compartment 420. Wherein, the first ventilation hole 810 can be provided with a plurality of, a plurality of first ventilation holes 810 are arranged on the side wall forming the wind cavity 80 in an array manner, and through the arrangement of the first ventilation holes 810, the cold air can be blown into the second compartment 420 more uniformly, so that the temperature difference at each position in the second compartment 420 is smaller. Of course, in other embodiments, the second compartment 420 may be in direct communication with the evaporator chamber 50.

In order to allow the air in the second compartment 420 to be circulated back into the evaporator chamber 50, as shown in fig. 3, the case 10 is further provided with a return air passage 90. The return air duct 90 has a first end 910 and a second end 920 disposed opposite to each other, the first end 910 communicating with the evaporator chamber 50, and the second end 920 communicating with the second compartment 420. Specifically, the second end 920 may be formed in a sidewall of the second compartment 420, or may be formed in a bottom wall of the second compartment 420. However, due to the inconsistent density of air at different temperatures, cold air will settle and hot air will rise; therefore, in the present embodiment, the second compartment 420 is located above the first compartment 410, the side wall of the box body 10 forming the second compartment 420 includes a top wall far from the first compartment 410, and the second end 920 of the return air duct 90 is formed on the top wall of the second compartment 420, so that the air with higher temperature in the second compartment 420 is circulated to the evaporator cavity 50.
